    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Hi all i was just wondering,on this bike (it has the 2 2 barrel carbs) there are 4 small nipples that are supposed to have hoses on them and connected to a plastic connector,on my bike they were missing when i bought it, the connector is now obsolete ie not available should these be capped off or should i macgyver something will it make any difference.I'd like to get it back as close to stock as i can THANKS !
 
I have not worked on a set of your carbs, so anything I say here is going to be pure GUESSWORK.

In general, these are not really all that different from four separate carbs. One of those nipples will likely be to provide vacuum to the petcock. On the four-carbed bikes, that would be #2. The four-carbed bikes had a "T" between 1&2 and 3&4 that had hoses attached. Those were vents for the float bowls. There was no fourth nipple on those carbs.

If your carbs are not on the bike, it will be rather easy to determine which one will provide vacuum to the petcock. Look into the engine side of the carbs. You will see a large-ish port on all of them that is the enrichening ("choke") circuit. One carb will have an extra hole in the same general area. That is the one that provides vacuum to the petcock.

To identify the other ports, maybe spray something through them to see where it goes? :-k

the two that are eqaul in size are vents
the small one is for vacuum
the odd man out is fuel and is the largest iirc
vacuum and fuel are on the right side carb
 
I'm not in front of mine at the moment, but I am trying to picture to which plastic connector you are referring that is obsolete....and nothing comes to mind.

Can you post a picture?
 
I think he has a california spec model they had an odd bit of extra plumbing
